DESCRIPTION
The L293B and L293E are quad push-pull drivers
capable of delivering output currents to 1A per
channel. Each channel is controlled by a TTL-
compatible logic input and each pair of drivers (a
full bridge) is equipped with an inhibit input which
turns off all four transistors. A separate supply in-
put is provided for the logic so that it may be run
off a lower voltage to reduce dissipation.
Additionally, the L293E has external connection of

sensing resistors, for switchmode control.
The L293B and L293E are package in 16 and 20-
pin plastic DIPs respectively ; both use the four
center pins to conduct heat to the printed circuit
board.
